DISK WHEEL.

Application filed Jul 19, 1920. Serial No. 397,479.

To all whom it may concern.

Be it known that we, CLAUDE K. MONT- -GOMERY and CLAUD R. TROMLEY, citizens of the United States, residing at Detroit, county of Wayne, State of Michigan, have invented a certain new and useful Improvement in Disk Wheels,-and declare the following to be a full, clear,.and exact descrip tion of the same, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to disk wheels and the object of the invention is to provide a disk wheel in which the disk when assembled is solidly secured to the wheel hub. Another object of the invention is to provide a device of the character described in which the disk is corrugated radially thereby providing a disk of exceptionally strong construction which will not bend under strain. A further object of the invention is to provide a corrugated disk adapted to fit over a wheel hub, the wheel hub being provided with a shoulder having corrugations thereon fitting the corrugations of the disk, the parts of the wheel when assembled binding the disk to the said shoulder. A still further object of the invention is to provide a disk wheel of the character described inwhich the disk isremovable from the hub by withdrawal of a single hub nut. These objects and the several novel features of the invention are hereinafter more fully described and claimed and the preferred form of construction by which these objects are attained is shown in the accompanying drawings in which- Fig. 1 is a sectionthrough a disk and hub embodying our invention. Fig. 2 is a perspective view of the disk.

:Fig. 3 is a perspective view of the wheel hub, with the disk removed.

Fig. 4 is a perspective view of an outer ring fitting the corrugations of the disk.

Fig. 5 is an elevation of the nut by which the hub parts and disk are secured together. Fig. 6 is a perspective view of a'portion of a brake drum adapted to be used with the wheel.

The wheel consists of a disk 1, shown more particularly in- Fi 2, and it is to be understoodthat a wl ieel rim may be secured to the outer edge of this disk in any approved manner. The disk 1 is fluted radial- If desired the member 4 may be a ring pro- 'vided with corrugations 5 and may be shrunk onto the hubv 3. The aperture 6 in the disk 1 is adapted to fit over the hub 3 so that the corrugations 2 fit the corrugated face 5 of the member 4. A ring or washer 7, as shown in Fig. 4, is provided with an aperture 8 adapted to be passed over the hub 3 and this ring 7 is provided with a corrugated face 9 fitting the corrugations 2 of the disk 1 at the center. The hub 3 is threaded'at 10 and on this threaded portion a nut 11, as shown in Fig. 5, is adapted to be threaded. As is shown in Fig. 1, the

nut 11 is provided with a flange 12 adapted to engage the outer face of the ring 7 when turned up. When theparts are assembled as shown in Fig. 1, the nut 11 is turned up on the threads 10 thereby tightly. binding the corrugated member 4 of the hub, the corrugated center of the disk and the corrugated ring 7 together. When this has been done a hub cap 13 is threaded onto the outer threads 14 of the hub 3 thereby providing a wheel of neat appearance. It is to be noted that by this method of securing the disk to the hub it' is impossible to rotate the hub in relation to the disk which would occur were it not for. thecorrugations. This type of disk wheel may be used for the driving wheels of a vehicle as well as for steering wheels asunder the 'most difficult driving conditions the disk cannot be loosened. To absolutely prevent the disk from loosening the threads 10 for the nut 11 may be left hand threaded and the threads 14 for the hub cap 13 may be right hand threaded. Thus when the nut 11 has been turned up tightly on the left hand threads the cap 13 -may be threaded onto the right hand threads until the flange 15 thereof tightly engages the outer edge of the nut 11. In this manner the disk is securely locked to the wheel hub and cannot come loose.

One of the particular "featuresof this invention is the ease with which the disk may be removed from the hub. In use an extra disk with rim and inflated tire.thereon may be carried on the rear of t e machine.

Should a puncture occur the hub cap 13 and nut 11 may be removed from the hub at which time the disk 1 and ring member 7 may be easily removed and the spare disk with the rim and inflated tire may be slipped onto the hub, and the ring 7 moved to position at which time the nut 11 may be turned up to bind the parts to ether and the hub cap threaded onto the ub. In this manner a very quick and simple wheel change may be made without the necessity of removing a series of bolts as is common in disk wheels. It is to be noted that no bolts are used with this disk wheel, the disk being secured to the hub by the fittingtogether of thecorrugations on the disk, hub shoulder and ring 7.

As shown in- Fig. 6 a brake drum 16 may be used with this device. This brake drum is provided with the usual flange and is apertured at the center to fit over the hub. The

' perpendicular face of the brake drum about the central aperture is provided with corrugations 17 similar to the corrugations 2 of the disk 1. In amembly the brake drum is first positioned on the hub with the corrugations thereof fitting thecorrugations of the shoulder 4. At this time the disk 1 is posi-,

tionedover the hub with the corrugations thereof fitting the corrugations 17 of the brake drum. The ring? is then slipped on the hub and the parts are bound together as before by the nut 11. In this m'anner the brake drum is secured to the wheel in a very solid manner and is held as strongly as though bolts were used. When the brake drum has been thus secured to the wheel the flange thereof projects inwardly in the proper position as shown in dotted lines 18 in Fig. 1. It is to be particularly noted that thea rture 6 of the disk may be considerably arger than the hub 3 and when the parts are secured together movement of the disk in relation to the hub is impossible even when very hea loads are carried by the wheel. To illustrate this let us suppose that there is a clearance of one-quarter of an inch between the edge of the disk adjacent the aperture and the wheel hub. When the parts are locked together and a heavy load is applied to the wheel the vertical pressure will be taken up by the radial flutings or corrugations which are in the horizontal position and thusmovement of the disk in is further to be noted that this disk and hub,

are not limited to use with a vehicle wheel but may be used with belt pulleys, fly wheels and wheels in general in which case the'interior of the wheel hub, which forms no art of this invention, may be varied to con orm to the use for which the wheel is designed.

From the foregoing description it becomes evident that the device is very simple and eflicient in operation, of stro construction, is easily assembled or disassembled and provides a disk wheel which accomplishes the ob'ects desired.

aving thus fully described our invention, its utility and mode of operation, what we claim and desire to secure by Letters Patent of the United States is- In a disk wheel, a hub having a flange provided with a radially corrugated outer face, a cylindrical portion adjacent the said face, a succeeding threaded portion adjacent the cylindrical portion, a second cylindrical portion adjacent and of less diameter than the said threaded portion, a second threaded portion adjacent the said second cylindrical portion "extending to the hub end, one of said threaded portions being left hand threaded, a tapered clamping member having an inner corrugated face complemental to that of the hub flange and apertured to fit the first cylindrical portion of the hub, the

twocorrugated parts being adapted to secure a radially corrugated disk therebetween, a nut having a flange engaging against the said tapered clamping member, and a second nut providing a ca for the hub end and having a cylindrica part engagin over the said second cylindrical portion 0% the hub with the inner end seating against the first nut.

In testimony whereof, we sign this specification. v
